BRISBANE — The defending champion Queensland Reds remained in the hunt for a playoff spot in Super 15 rugby with a 19-13 win over the Otago Highlanders Friday. Queensland is in second place in the Australia conference, one point behind the ACT Brumbies, who will have a chance to extend their lead when they play New South Wales on Saturday in Sydney. The Highlanders, in fourth place in the New Zealand conference, have no chance of making the six-team playoffs. In Hamilton, the Canterbury Crusaders scored three contentious tries to beat the Waikato Chiefs 28-21. — Agencies
